HOSE CLAMP.

Application filed 'nece'inber 3, 1925., Serial No. 73,005.

T 0 all whom it may concern: a I

Be it known that I, SAMUEL C. LAvnNnnn, a citizen of the United States, residing at Slim, in the county of McCurtain and State of Oklahoma, have invented certain new and useful Improvements in Hose Clamps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to hose clamps and more particularly to a hose clamp embody ing a lever whereby it may be tightened'to clamp the hose.

An important object of the inventlon is to provide an'improved form of lever as well as an improved clamp having portions with which the lever coacts to cause tightening of the clamp. I 7

These and other objects I attain by the construction shown in the accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein t Figure 1 is a perspective view of a hose clamp constructed in accordance with my invention; I

Figure 2 is a vertical sectional viewtherethrough.

Referring now more particularly to, the drawing, the numeral 10 indicates a metal band, the major portion of the body of which is slotted, as indicated at 11, so that the body of the hose may bulge therethrough to prevent slipping of the clamp upon the hose. This slot terminates short of the ends 'ofthe band and one end of the band is formed with, a longitudinally extending series of openin s 12 and at this extremity is formed with an eye 13 which is centrally notched, as at 14. Through the sections of the eye thus produced, a pivot pin 15 is directed and passes through a lever 16 which arranged at the-outer face of the band. The

7 working end 18 of the lever is hooked, as

shown, and is formed in its end with a notch 1.9 adapted to receive the metal at the the lever then has its placed thereon by the lever.

'ing formed in one end thereof edge of the projections or teeth 17. The teeth 1? are ings 12. r

In the use of the band, the band is first placed about the hose with the extremity 20 of the last named end portion arranged beneath the end portion having the openings 12. This extremity is provided with a hook 21 inclining away from the free end of the extremity and this hook is engaged in one ofthe openings 12. To tighten the band,

into engagement with one of the projections 17, the notch 19 receiving the end wall of the projection after which the lever is forced in the direction of the arrow on Figure 2 with the result that the. band is constricted and the extremity 20 and end portion bearing the openings 12 caused to have movement in opposite directions. This will cause the hook to slide out of the openingwith which it is engaged and align'with a second opening through which it will pass because of the tendency of these sections to remain in engagement, one being forced outwardly by the resiliency of the hosewhile the otheris drawn inwardly by the strain This operation is continued until the band is sufiiciently tightened. 1

It will be obvious that a device of this character may be veryreadily and cheaply produced and is very readily applied to the" any sort.

hose without the use of tools of It will also be obvious that the construction hereinbefore setforth is capable of a certain range of change and modification with out materially departing from the spirit of the invention and I accordingly do not limit myself to such specific structure except as hereinafter claimed.

I claim 1. A hose clamp comprising a band hava longitudinally extending series of openings, the extremity" of said end having pivoted thereto a lever swingablc in a plane including the longitudinal axis of the band and a plurality of teeth formed. upon the outer sur face of theopposite end of the band with which one end of the lever is adapted to engage, the extremity of the last named end of the band having a hook adapted for engagement in the openings of the first named spaced similarly to the openworking end brought b rality end of the band to prevent return movement of the last named end of the band after shifting thereof by said lever.

2. A hose clamp comprising a band having formed in one end thereof a longitudinally extending series of openings, the extremity of said end having pivoted thereto a lever swingable in a plane including the longitudinal axis oi the band and a pluof teeth formed upon the outer surface of the opposite end of the band with which one end of the lever is adapted to engage, the extremity of the last named end said lever having a notch, each of said teeth having a relatively thin Wall adapted for engagement with the notch and spaced from the outer face of the band.

In testimony whereof I hereunto afiix my signature.

SAMUEL G. LAVENDER.
